Have code P2238 - what could be the cause ?


code p 2238 has 3 references
heated oxygen sensor(HO2S) 1 bank 1,positive current control---circuit low ====causes ---wiring short to ground ---HO2S
second reference
oxygen sensor (O2S) 1 bank 1 positive current---circuit low====causes ---wiring short to ground ---O2S
3rd reference
HO2S 1 bank 1--implausible signal===causes ---wiring---short to positive ---short to ground ---HO2S---ECM
as the heated oxygen sensor is common with wiring problems indicated , maybe changing it will fix the code
note
HO2S is the sensor in the exhaust manifold in bank1 before the cat converter

Where is Bank 2 sensor 1 oxygen sensor on my 2007 tundra 5.7


Bank 1 is always the sameside of the engine as the number one cylinder.
Bank 2 is always the other side of the engine.
Sensor 1 is always before the cat
sensor 2 is always after the cat.

Cylinder number 1 on this engine is on the drivers side. So bank 2 is the passenger side of the engine and sensor 1 will be located before the catalytic converter.

- Cylinder bank number one is the bank that contains number one cylinder.

Cylinder #1 on right side.

- The first oxygen sensor in cylinder bank # 1 is numbered O2 Sensor 1/1.
- The second oxygen sensor in cylinder bank # 1 is numbered O2 Sensor 1/2.
- A third oxygen sensor in cylinder bank # 1 would be numbered O2 Sensor 1/3.
- The first oxygen sensor in cylinder bank # 2 is numbered O2 Sensor 2/1.
- The second oxygen sensor in cylinder bank # 2 is numbered O2 Sensor 1/1.



- If a V-6 or V-8 vehicle only uses one downstream Heated Oxygen Sensor (HO2S) it is numbered O2 Sensor 1/2, even if it uses two upstream HO2S.

Had local part store pull code. O2S heater CKT malfunction 1/1


This fault indicates a problem in the oxygen sensor heater circuit, bank 1 sensor 1.
Your vehicle is equiped with four oxygen sensors total. Two upstream and two after the catalytic conveter that monitor emissions and converter effeciency. The front sensor on the left (drivers side) bank requires replacement. The heaters are used to bring the sensor up to operating temperature sooner.

2005 gallant with O2 sensor engine light is one...how do I fix it?


have the engine light code scanned, and it'll tell you if it's bank 1 sensor 1, bank 1 sensor 2, bank 2 sensor 1, bank 2 sensor 4.

Bank 1 is on the same side as Cylinder 1
Bank 2 is on the opposite side of Cylinder 1

Sensor 1 is located before the catalytic converter.
Sensor 2 is located after the catalytic converter
